Asphalt pouring device



' May 16, 1933. c. H. WHYMER ASPHALT POURING DEVICE Filed Jan. 20, 1931 Patented May 16, 1933 UNITED STATES CHARLES H. WHYMER, F ATHENS, ILLINOIS ASPHALT POURING DEVICE Application filed January 20, 1931.

This invention relates to pouring cans especially designed for pouring hot asphalt or similar filling material into the crevices of cement or similar roadways. An object of the invention is to provide a tank having a bottom inclined in the direction of the pouring spout so as to permit the contents of the tank to be readily discharged, the tank being equipped with a handle which permits of the pouring operation belng performed by the workman carrying the tank at his side without stooping over, the tank being equipped on the inclined bottom with legs which permit of the can being set down and. filled at the work without tipplng over. A further object is to provide the tank with a screen which slopes oppositely to the inclined bottom of the tank and prevents the asphalt from clogging or otherwise obstructing the pouring spout.

A still further objectis to provide a novel valve for opening and closing the pouring spout, the valve having a vertical stem which extends upwardly through the tank and is provided with a lateral grip at the top positioned within convenient reach of the operators hand which grasps the handle so that the valve may be manipulated by simply closing one of the fingers around the grip of the stem without interrupting the pouring operation.

With the above and other objects in view the invention consists in certain novel details of construction and combinations of parts hereinafter fully described and claimed,

it being understood that various modifications may be resorted to within the scope of the appended claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawing forming part of this specification:

Figure 1 is a longitudinal sectional View of an asphalt pouring device constructed in accordance with'my invention,

Fig. 2 is a cross sectional view on the line 22 of Fig. 1 showing the filling opening in the top of the tank, and

Fig. 3 is a cross sectional view on the line 'jection of the seat being screwed into and unscrewed Serial No. 510,049.

33 of Fig. 1 showing the screen and valve stem passing therethrough.

Referring now to the drawing in which like characters of reference designate similar parts in the various views, 10 designates a container or tank which preferably is formed of sheet metal. The wall of the tank is preferably cylindrical and the bottom 12 of the tank slopes obliquely downwardly, as shown, to permit of the hot asphalt sliding freely downwardly thereupon to the pouring spout. The top 13 of the tank is provided with an elongated filling opening 14 disposed laterally of the central diameter of the top and ofsuflicient size to permit of the operator viewing the contents of the tank therethrough from time to time to note the height of the contents.

The tank is provided with a strap handle 15 at the top which permits of the tank being carried at'the side of the workman, preferably the combined heights of the tank and handle being such that the workman may carry the tank along at his side without stooping over and position the pouring spout slightly above the crack or crevice in the roadway. I Y The pouring spout 16 is preferably cylindrical in contour and is located at the bottom of the wall of the tank at its juncture with the lowest point in the inclined bottom 12 of the tank. The axis of the pouring spout is parallel withthe plane'of the inclined bottom; 7 v I A conical valve seat 17 is threaded into the pouring spout and isprovicled with a pro- 18 having wrench faces 19 to permit out of the pouring spout.

A conical valve 20- is seated in the valve seat and preferably may be formed of rod material which is pointed at the lower extremity to constitute the valve. The rod is directed parallel with the inclined bottom 12, as shown at 21, and is thence bent'to extend vertically upwardly, as shown atl22, through the tank'to constitute the valve stem. The upper end portion of the valve'stem is slidably fitted in an opening 23111 the tank top, and near the horizontal grip portion of the handle 15 is directed abruptly laterally, as shown at 24, to extend parallel with said horizontal portion of the handle and in close proximity thereto. The lateral bent grip 24 of the valve stem may thus be raised or lowered by pressure of the finger thereupon without releasing the hand from the handle, to manipulate the valve.

A screen 25 is disposed in the tank above the pouring spout and is preferably formed of sheet metal having rows of perforations 26 and also being provided with a slot 27 through which the valve stem 22 extends. The screen is positioned to slope obliquely downward to the inclined bottom 12 of the tank and in a reverse direction to the slope of said bottom. By thus positioning the screen in the tank, the asphalt or other filling material is prevented from clogging or otherwise obstructing the pouring spout while, at the same time, the free gravitation of the as phalt along the sloping bottom 12 is in nowise impeded by the screen.

The tank is provided on the bottom below the pouring spout with a short leg 28. Also the tank is provided with a rear leg 29 disposed near the upper end of the sloping bottom, as shown in Fig. 1. Both legs are preferably formed of strap metal and are respectively of suificient height to permit of the can being set down upon the work from time to time, as desired, for replenishing or other purposes. The height of both legs also is preferably such that when the can is set down the pouringspout is in close proximity to the crevice being filled.

It will be observed that the inclined bot.- tom 12 forms a guide to properly position the similarly inclined portion 21 of the Valve with respect to the valve seat, and that the slot 27 in the screen 25 also coacts with the inclined bottom of the tank in performing the same function of guiding the valve accurately into the seat after each withdrawal therefrom.

It will be further pointed out that by virtue of the spout being unobstructed by the handle or other parts of the device and, when in operation, being disposed just above the crack being filled, the operator may readily see exactly where the flow of material is going so that accuracy in pouring is enhanced. Furthermore, by virtue of the spout bein positioned in close proximity to the crac: during the pouring operation, the device may beoperated in windy weather equally as well as in calm weather, without waste of mate rial.

Having thus described the invention, I claim:

An asphalt pouring device comprising a cylindrical tank having a downwardly sloping bottom terminating in a pouring spout projecting from the wall of the can at the lowest point thereof in alinemen-t with the bottom, a screen having a bottom fiat edge supported on the bottom at about the center thereof and having an arcuate edge engaging the side wall of the tank, said screen sloping downwardly to the bottom and coacting therewith in forming a V-shaped trough whereby a space exists for strained asphalt below the screen contiguous to the spout, said screen having a slot therein, and a rod valve for closing the spout projecting through :the slot and having a pointed end directed at a downward angle to the rod and lying along the sloping bottom of the tank,

said stem beingguided by the walls of said slot and said pointed end being guided by said slopingbottom during movement of the rod valve to open and close the spout.

In testimony whereof I afiix my signature.
